I asked Kino back in 2001 about the differences between their VHS and their then just-released DVD, and they sent me a lengthy document containing a list of differences (download it here). The VHS was what Kino called the "English version," whereas the DVD was the "German version." The two versions were shot separately for domestic and foreign exhibitions. Actors had to perform each scene twice for the two versions, thus resulting in different body movements and facial expressions. There are scenes not found in the VHS as well. So expect to see a very different version. The 2015 Blu-ray and DVD are also based on the "German version."
Kino also made another lengthy document on the differences between the restored and unrestored versions of "Metropolis." The webpage on which it was found has long been gone, but I saved a copy. If anyone wants it too I'll put it up.
